A pity to leave this one languishing and I can only offer a crumb of help. The male voice sounds like one of the announcers at All India Radio's national channel English service. Why AIR South would be transmitting the national channel at that time of night is a different matter.

Well perhaps that was a slightly useful suggestion that might prompt others to agree or otherwise.

I checked my toth recordings from the last couple of days. I don't hear the same as what you have Patrick, but I hear Iran, which dominates here in the evenings. Could it be that? The music at the very beginning of the clip sounds suspiciously like the kind of toth music Iran might play.

Thanks for your help, mates !
John : this one is from June, 17th. I re-checked this TOTH recording, and at 2156, I found this female voice : https://vocaroo.com/i/s0V3szKA5zE7
Maybe from the same station ?

The female certainly sounds like Iran, the music is "Wish You Were Here" by Pink Floyd
